Title: Improvements in and relating to the recording and reproducing of sound
IPC: G11B7/00
Filed: 1948-06-24
Abstract: 652,664. Sound-film apparatus. PAILLARD. SOC. ANON., (formerly PAILLARD & CIE. SOC. ANON.). June 24, 1948, No. 17009. Convention date, July 10, 1947. [Class 40 (ii)] [Also in Group XX] In an optical sound record, the sound track is formed in a series of arcuate rows displaced from each other, longitudinally along the film, and consists of a series of images which are equidistant along the sound track in the absence of a sound signal, and are displaced, when modulated by sound, by distances varying in accordance with the sound. The recording apparatus comprises an audio-frequency generator S, Fig. 1, feeding a low-frequency amplifier ABF controlling a frequency modulator M, a light modulator ML controlled by the frequencymodulated tension issuing from a power amplifier AP, an optical system O and a rotary scanning disc B serving to record upon a film F a series of images of a slit which succeed one another in accordance with the frequencymodulated tension. Modulation may be effected with the aid of a high-pressure mercury lamp or a supersonic valve functioning on the Debye- Sears effect, when intensities may be modulated up to 100 kcs./sec. The images on the film may be well contrasted by converting the signals, by known means, into those having a rectangular waveform. The reproducing apparatus comprises a constant light source O<SP>1</SP>, a rotary scanning disc B<SP>1</SP> with which a beam is swept across the film F, and a photo-electric cell 13 generating electric impulses which are amplified by the amplifier A and passed to an amplitude limiter LA, a selector D and a detector DE. The detector currents are amplified by an amplifier BF and passed to a loudspeaker HP. The film F may be scanned during recording and reproducing by means of a scanning disc illustrated in Figs. 3 and 4, in which the image of a slit 6 produced by the light from a stationary source 7 is reflected by mirrors 11 through lenses 10 on to the film F. A condenser 8 enables a solid angle a of beam to be produced so that an image of even intensity appears on the film during the whole of the scan, except for a short space of time at the end of a scan when two of the lenses 10 project an image simultaneously upon the film F. The optical system is so designed that the intensity of light, during this short period, passing through individual lenses 10, is such that the sum of the light falling on the two lenses simultaneously is constant and equal at all times to the whole of the light falling on one lens working singly. The source of light may be replaced by a cathode-ray tube in which the beam is deflected at the desired rate and simultaneously electrically modulated.

Abstract: 1,070,053. Track propulsion systems. DISTINGTON ENGINEERING CO. Ltd. May 6, 1966 [April 22, 1965], No. 17098/65. Heading B7L. [Also in Division F1] A transport apparatus comprises a carriage including two trucks 10, 11 each having wheels (not shown) which bear on a rotating rail (not shown) at a variable angle of skew and move the truck along the rail upon being rotated thereby and also having a control member 15, 16 respectively to vary the angle of skew, a common load-carrying member 12 suspended from the trucks 10, 11 by support members 13, 14 respectively pivoted to the member 12 at longitudinally spaced apart points and also pivoted to the respective trucks, and hydraulically coupled piston-in-cylinder devices 19, 20, 17, 18 interconnecting the control members 15, 16 and the support members 13, 14 to tend to equalize the speeds of the two trucks. The cylinders of the devices 19, 20 are rigidly connected together by a member 23 and are connected by a cable 24, having a sheath fastened to the trucks 10, 11, to the control lever 15. The pistons of the devices 19, 20 are integrally connected and pivoted to the control member 16. The cylinders of the devices 17, 18 are pivoted to members 21, 22 fixed to the member 12 whilst their pistons are pivotally connected to the supports 13, 14, respectively. The devices 17, 19 and 18, 20 are interconnected by hydraulic flow lines 25, 26 and 27, 28 respectively so that all pistons must move in unison. By moving the lever 15 to the right the truck 10 is driven to the right. At the same time the cable 24 causes the pistons and cylinders of the devices 19, 20 to move together and move the lever 16 to the right and drive the truck 11 to the right, i.e. assuming the supports 13, 14 are vertical. Should the truck 11, e.g. move faster than the truck 10, the truck 11 will pivot the top of the support 14 to the right, and cause the piston of device 18 to increase the pressure in those parts of the four devices shown hatched. This causes the lever 16 to move to the left and slow down the truck 11. Also the two devices 17, 18 move in unison so that the member 13 is tilted in the reverse direction by the same amount when member 14 is tilted and vice versa, maintaining the member 12 in an intermediate position between the two trucks.
